SUMMIT, N.J., April 25, 2018 /PRNewswire/ -- Following successful Phase 1 clinical trials, the Toca regimen – a new immunotherapy for patients with recurrent brain cancer – has advanced to a Phase 3 study, which is currently underway. The trial is being conducted at 67 sites across the United States, Canada, Israel and South Korea, including at Atlantic NeuroSurgical Specialists (ANS) Brain Tumor Center, one of three clinical trial sites in New Jersey. In this surgical study, patients are randomized to either standard of care treatment or the Toca regimen. Enrollment is expected to complete in this trial by the end of 2018.
"Toca 5 uses a virus to stimulate a patient's own immune system and attack recurring high-grade gliomas – glioblastoma and anaplastic astrocytoma," explains Dr. Yaron Moshel, a board-certified neurosurgeon at ANS.
Patients randomized to the Toca regimen receive an investigational treatment that involves two discrete steps. During the first step, patients receive Toca 511 (vocimagene amiretrorepvec), a replicating virus that selectively infects cancer cells, at the time of surgery. After a few weeks, they then take cycles of Toca FC (extended-release 5-fluorocytosine), a potent anti-cancer pill that kills cancerous cells and activates immune cells selectively against cancerous ones, leaving healthy cells unharmed.
"Data from Phase 1 testing of the Toca regimen showed a favorable safety profile, complete tumor shrinkage, and extended patient longevity compared to other therapies," Dr. Moshel continues.
With the current standard of care, newly diagnosed patients with glioblastomas have a median survival of approximately 14 to 16 months. After recurrence, median survival is typically seven to nine months.
"In contrast, Phase 1 results of the immunotherapy trial showed median longevity of 14.4 months for patients with recurrent disease and patients with complete tumor shrinkage are still alive almost 3 years after starting the Toca regimen," adds Dr. Moshel. "These results are encouraging – for patients, their loved ones and the medical community – and we look forward to sharing further findings from Phase 3 within the next 18 months.
